Configuring Elasticsearch

You can configure the Elasticsearch on a single node or across multi-nodes.

1. Browse to the elasticsearch-7.17.1/config folder.
2. Edit the following properties in the elasticsearch-7.17.1/config/elasticsearch.yml file.

   cluster.name

   The name of the cluster.

   By default, the application uses cluster.name =es-cluster.

   If you modify the value of the cluster.name property, you must also update the elastic_cluster_name property in the env_settings.ini file.

   node.name

   The descriptive name for the node.

   indices.query.bool.max_clause_count

   Maximum number of clauses a Lucene BooleanQuery can contain. Update the value to 10000.

   network.host

   The IP address of the host to make Elasticsearch service accessible from other workstations in the network.

   path.data

   The file path where the Elasticsearch stores the data.

   data folder in the <elasticsearch installation directory>

   path.logs

   The file path where the Elasticsearch logs are generated.

   logs folder in the <elasticsearch installation directory>

   http.port

   The HTTP port, "http.port".

   transport.port

   The TCP port.

   discovery.type

   The Elasticsearch node elects itself as master and does not join a cluster with any other node. For more information, see Single-node discovery.

   transport.compress

   Enable compression on the Elasticsearch response. By default, the value is true.

   cluster.initial_master_nodes

   The IP address:TransportPort of the initial master node information in an array format. For example, ["IP address:TransportPort"].

   discovery.seed.hosts

   The IP address:TransportPort of the self-node and other nodes in an array format. For example,

   discovery.seed_hosts: ["IP address:TransportPort"], ["IP address:TransportPort1"]

3. Restart the Elasticsearch service for changes to take effect.
